Not sure why a parent would go for this method of punishment. Sure, the child disobeyed her, but twerking is something she'd have grown out of anyway. It would just be following a "fad".

The act itself isn't that serious, and she'd have eventually forgotten about it. What she won't forget, is that her mother opted to humiliate her daughter in public, instead of trying to be, I don't know, more understanding of her daughter's age and mindset?

This is all coming from me being pretty lenient to everyone, so I guess it doesn't mean much xD
